ADJUSTABLE MEASURING-CHAMBER FOR FAUCETS.

SPECIFICATION forming part of Letters Patent No. 341,518. dated May 11, 1886.

Application filed March 6, 1885.

To all whom, it may concern.-

Be it known that I, Asa W. STRAIGHT, a citizen of the United States, residing at Ypsilanti, in the county of VVashtenaw and State of Michigan, have invented a new and useful Device for Measuring Fluids, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to a new process of measuring fluids. The fluid is drawn from a reservoir into a can or receptacle closed at the top to form an air-chamber. .The capacityof the ai r-chamber can be varied by raising or lowerin g an air-escape tube, which passes through a packing-box at the top of the air-chamber. At the base of the air-escape tube is a valve, which is operated by a float. The. can or receptacle is fixed to the top of a double-acting faucet. The faucet is connected by a lead pipe or directly to a reservoir. As the fluid passes into the receptacle it raises the float. The rising of the float closes the valve to the air-escape tube, and thus prevents the escape of the fluid and of more air, and thereby the entrance of more fluid.

The objects of my invention are, first, to sub stitute a single measure for a set of measures; second, to measure any desirable quantity at a single run; third, to obtain in foaming liquids the exactaniount of the fluid desired without waiting for the foam to settle or running it over the edge of the measure; fourth, to render waste from sloppage absolutely impossible; fifth, to draw the most inflammable fluids in close proximity to lights or fire without danger; sixth, to measure fluids in the dark; seventh, to provide a measure in which dirt cannot collect; eighth, to economize space. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a side and external View of the fluid-measure as set for operation. Fig. 2 rep resents the float in a position taken when not raised by the fluid and the air-escape tube open at the base. Fig.3 is a vertical section of the can and faucet. The cap in the faucet is left entire to show the hole in the side of the cap. The dotted lines in the'cap represent the inside of the cap. The float and air-es- Serial No. 157,993. (No mod-l.)

cape tube are also entire. The float is raised and the escapetube is closed. All that part of the can or receptacle between the dotted fluid-line at the base of the float and the 1 top of the can or receptacle constitutes the air-chamber.

Si inilarlel ters refer to similar parts throughout the several views.

. In Figs. 1 and 3, A is a can or receptacle, which is closed at the top and constitutes an air-chamber. The capacity of the air-cham- -ber is regulated by raising or lowering the air-escape tube 0. The receptacle is placed above and connected to a doubleacting faucet, B B. The faucet B B is connected to a tank or reservoir by a lead pipe, (7. The fancet B B consists of a tube, F F, Fig. 3, which is stopped by a revolving cap, H, open at the top. The cap H is operated or turned by a lever, c. A hole, G, is in the side of the cap H, so located as to face the tube F F of the faucet B on the side toward the lead pipe (I when the lever c is in a certain position, or parallel with the faucet B B and pointing toward its mouth. Fig. 1 represents the lever in this position. \Vhen the hole G, Fig. 3, in the side of the cap H is in this position, facing the entrance of the faucet B B, the fluid can pass from the reservoir through the lead pipe (I, and through the hole G into the cap H, and out at its open top into the receptacle A. \Vhen the lever e is reversed from this position, delivery is obtained from the receptacle A, the fluid passing through the cap H and hole Gand out at the mouth of the faucet B B. Vheu the lever c is in a certain other position, as at right angles to the faucet B B, the tube F F of the faucet B B isclosed from both directions, and the fluid can neither pass into the receptacle Anor out of it.

An air-escape tube, 0, Figs. 1 and 3, passes through a packing-box, K, at the top of the receptacle A.

At the. lower end of the air-escape tube 6, Fig. 2, is a valve, j, which is operated by a float, I, in connection with the levers O 0.

An adj ustablc horizontal bar, M, is attached at or near the top of the escape-tube 6. One end of the bar M rests against a gage-standard, N. The gage-standard N is attached to thetop of the receptacle A at a convenient distance from the escape-tube e, and so as to spring against the horizontal bar M.

In the gagestandard N, Fig. 2, a groove, I, is pressed, in which there are slots R R, at desirable distances from each other, into which the end of the bar M slides as the escape-tube e is raised and lowered.

The slots R R in the gage-standard N, Fig. 2, are marked 1 qt, 2 qt, &e., or in any desirable scale, and when the bar M slides into the slot marked 1 qt. or 2 qt, &c., it indicates the hei ht of the ainescape tube 0 and the complementary capacity of the airchamber in the can or receptacle A, Fig. 3, and that one quart ortwo quarts, &c., respectively, must flow into the receptacle A to raise the float I so high as to cause the valve j to press against the escape-tube e and prevent the l'urtherescape of air. The air-escape tube 0 being closed, Fig. 3, no more air and none of the fluid can pass out of the recepta cle and no more fluid can pass in.

In my invention the action of the fluid checks the flow of the fluid into the receptacle automatically.

I do not confine myself to any particular 'avalve at the base.

form of levers. Indeed, I have obtained the desired result by attaching a rod perpendicularly to the center of the float and adjusting Then by inserting the perpendicular rod into the escape-tube the ascension of the float will close the air-escape tube. The float may also be made nearly as large as the can and float loosely on the inside.

Therefore What I claim, and desire to secure by Letters Patent, is

The can or vessel A, closed so as to form an air-chamber, and having an adjustable aireseape tube, 0, furnishedwith a valve, j, and float I, passing through its top, which is vertically adjustable, so as to allow the escape of such a quantity of air from the vessel as is necessary to admit into the vessel the amount of fluid that it is desired to draw, the escape of more air or of the fluid through the escapetube being prevented by the valve, which is closed by the float when the fluid has risen to such aheight in the vessel as to expel the said quantity of air, all substantially as set forth.
